Hernández-Hernández E.; Palao, J.M. (2013). Design and validation of a set of observational instruments to assess a team's match execution in volleyball. Journal of Sport and Health Research. 5(1):43-56.



The aim of this study was to design and validate a set of observational instruments to assess a team's game system in the initiation to volleyball. The set of observational instruments allows us to assess the execution of different team systems (universal players, four spikers and two setters, four spikers and two universals, or five spikers and one setter) in their various offensive and defensive aspects during the game. A review of the specialized literature was done to establish criteria for observation. The content validation of the instrument was established qualitatively (degree of understanding, appropriateness of wording, relevance of questions, etc.) and quantitatively (global assessment on a scale from 0 to 10) through agreement and consensus by ten expert judges. All instruments had an evaluation greater than 8.5 out of 10 by the experts. From the results, it can be established that all the instruments have content validity to evaluate the execution of team systems during the game in the initiation to volleyball.
